1. A user equipment for use in a wireless communication system, the user equipment comprising:
a communication module; and
a processor for controlling the communication module,
wherein the processor is configured to,
receive a plurality of first downlink control information (DCI) formats for downlink scheduling, wherein each of the plurality of the first DCI formats includes Nc-bit counter downlink assignment index (c-DAI), and Nc is one of 1 and 2;
receive a second DCI format for scheduling a physical uplink shared channel (PUSCH), wherein the second DCI format includes 2-bit uplink DAI (UL-DAI); and
transmit a hybrid automatic repeat request (HARQ)-acknowledge (ACK) codebook for the downlink scheduling via the PUSCH,
wherein a bit size of the HARQ-ACK codebook is associated with O having:
i) a first value: 4*floor(j*C/4)+V, or
ii) a second value, which is larger than the first value by 4, where
j is a counter value for a case that a value of a Nc-bit c-DAI is less than or equal to a value of a previous Nc-bit c-DAI within a plurality of received Nc-bit c-DAIs,
C is 2Nc,
V is a value of the 2-bit UL-DAI, and in a range of 1 to 4, and
floor is a flooring function.
